Unraveling productivity-enhancing genes in Chinese hamster ovary cells via CRISPR activation screening using recombinase-mediated cassette exchange system.
Article in Metabolic engineering, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Chinese hamster ovary (CHO) cells, which are widely used for therapeutic protein production, have been genetically manipulated to enhance productivity. Nearly half of the genes in CHO cells are silenced, which are promising targets for CHO cell engineering. To identify novel gene targets among the silenced genes that can enhance productivity, we established a genome-wide clustered regularly interspaced short palindromic repeats activation (CRISPRa) screening platform for bispecific antibody (bsAb)-producing CHO (CHO-bsAb) cells with 110,979 guide RNAs (gRNAs) targeting 13,812 silenced genes using a virus-free recombinase-mediated cassette exchange-based gRNA integration method. Using this platform, we performed a fluorescence-activated cell sorting-based cold-capture assay to isolate cells with high fluorescence intensity, which is indicative of high specific bsAb productivity (q
